Silver ores - Danafloat

Silver ores The most common silver-bearing minerals recovered by flotation are argentiferous galena, native silver, argentite (Ag2S) and tetrahedrite (Cu,Fe,Ag) Sb4S3). Often these minerals float with the base metals such as copper and lead sulphides or are the primary target mineral (tetrahedrite).

Flotation of Silver Bearing Minerals from Sulfide Ores

Mar 19, 2018  Silver is an economically important component of many complex, massive sulfide ores, and often is produced as a byproduct during recovery of base metals from sulfide deposits. About two-thirds of the world’s silver resources are contained in base-metal sulfide deposits (Reese, 1991). These ores are beneficiated almost exclusively by flotation.
